. OIL-BURNER.

Application filed March 8, 1921.

To all whom it may concern:

Be it known that I, ALEXANDER O. TnsoH, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil-Burners; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to an improvement in oil burners, and more especially to a burner which is adapted for use in connection' with the heavier liquid hydrocarbons.

The general object of the invention is to provide a burner which will have associated therewith, means for supplying a suflicient proportion of air which will be thoroughly intermingled with the particles of hydrocarbon in such a manner as to insure a complete combustionr A more specific object of the invention is to provide means for distributing the liquid fuel over the burner when the latter is hot, so as to vaporize the same and afterward to mix the vaporized fuel uniformly with the air so that the fuel will be thoroughly consumed, and produce the maximum amount of heat. 7 i

A further object of the invention is to provide means associated with the burner to convert a portion of the fuel which might otherwise be deposited in the form of carbon or soot into water gas, which is suppliedwith suflicient air to burn freely, thus greatly aiding the production and maintenance of a hot flame and complete consumption of the fuel.

My invention is capable of a great many adaptations and uses. Infact it may be substituted for many of the gas and liquid burners now in use which only operate successfully with the lighter and more expensive fuels.

In the present application, for the sake of illustration I have shownmy invention associated with a furnace.

In describing the invention reference will be had to the accompanying drawings, in which:

Figure 1 is a vertical sectional view of a portion of a furnace with my invention applied thereto.

Fig. 2 is a plan view of one of the devices for supplying air to the burner.

Serial No. 450,547.

Fig. 4 is a plan view of the burner base and valve. Referring more specifically to the drawings, the numeral 5 designates the base on whlch the furnace is supported. and provided with the usual ash door 6. The furnace has the usual heating drum 7 and in place ofthe usual coal grate I provide an annular supporting plate 8 to proved burner is attached.

The burner includes a substantially circular base 8, which is provided with an annular series of air inlet openings 10, which are controlled by a rotary disk valve 11. The burner base is formed witha central upstanding boss 12, on which is centrally mounted, a circular convex burner plate 13. The fuel supply pipe 14 extends upwardly through the center of the boss 12 and plate 13, and the supply of fuel is controlled by a valve 15. Extending upwardly through the plate 13 near its periphery is a Water supply pipe 16 provided with a control valve 17.

The burner plate is provided with a plurality of concentric burners which receive asbestos wicks 18 which become saturated with the fuel as it is supplied from the pipe 14, and spread outwardly overthe plate. Surrounding the wicks 18 and concentric therewith, is a groove 19, which is adapted to receive water as the same i supplied through the pipe 16. Outside of the groove 19, the burner plate is provided with a concentric series .of air inlet openings 20, and outside of these openings is another series of air inlet openings 21, the latter in the present instance being shown in the shape of arcuate slots. The air which is supplied through the openings 10, passes upwardly through the openings 20 and 21 in the burner plate, and mingles with the fuel as it becomes vaporized by the passage over the hot plate 13. A pin 22 is secured to the rotary disk valve 11 and extends upwardly through one of the slots 21 for controlling the valve, and if desired, means may be attached to the pin 22 for controlling the same from outside the furnace The burner base 9 and plate 13 are further provided at one side thereof with a comparatively large auxiliary air inlet opening 28, to which is attached the goose neck 24 for directing air downwardly on to the center of the burner plate. The goose neck is secured in position by the flange 25 and is which my improvided at its end with the constricted outlet 26 so that the air passing therethrough will be directed toward the center of the burner plate, and aid in spreading the fuel uniformly outwardly over the plate. The amount of air passin through the goose neck is controlled by the butterfly valve 27, which is provided with a handle 28 which may be provided, if desired, with an extension accessible from the outside of the furnace.

A deflecting drum 29 may be inserted in the furnace above the burner in order to deflect the heat toward the heating drum 7. From the foregoing description, it will be seen that I have provided a burner which is thoroughly practical and in which means are provided for thoroughly mixing a sufficient quantity of air and water vapor with the fuel, so that heavy liquid may be efficiently burned therein, and complete combustion effected.

I have described and illustrated only one adaptationpf the device, but it will be evident that the devicemay be used in various other ways and in other combinations, and forced draft may also be used if desired.

It will, therefore, be understood that it is not my desire to limit the invention to the precise structure herein shown and described, but that various changes in the structural details and applications of the device may be made within the scope of what is claimed without departing from the spirit ofthe invention.

I claim as my invention:

1. In an oil burner, a circular burner plate, means for supplying liquid fuel to the center thereof, a plurality of concentric wicks set in said plate for absorbing the fuel, means for inducing a current of air downwardl onto.

the plate 'to spread the fuel uni ormly toward the periphery of the plateand over said wicks, and a concentric series of perforations through the plate near its periphery, for supplying air to mingle with said fuel.

2. In an oil burner, a circular plate, means for supplying fuel, means for inducing a current of air downwardly onto the plate to spread the fuel uniformly toward the periphery of the late, a plurality of concentric wicks set in said plate for absorbing the fuel,.means for supplying water to the surface of ,said plate, outside of the wicks,

and a series of perforations through the plate near its periphery for supplying air to mingle with said fuel and water as they become vaporized.

3. In an oil burner, a circular convex burner plate, a liquid fuel pipe extending up through the center of said plate and discharging fuel over its surface, means for directing air downwardly over the said plate to spread the fuel and start the combustion, a plurality of concentric wicks set in said plate for absorbing the fuel, means for supplying water to the surface of the plate outside of the wicks, and a series of perforations through the plate near its periphery for supplying air to complete the combustion.

4. In an oil burner, a circular convex burner plate, means for supplying liquid fuel to the center thereof, means. for-inducing a current of air downwardly onto the plate to spread the fuel uniformly toward the periphery of the plate, a plurality of concentric wicks set in said-plate for absorbing the oil, a groove in the upper surface of the plate outside of and concentric with said wicks, means for supplyingwater to said groove, and a concentric series of perforations through the plate near its periphery for supplying air to mingle with said fuel and water as the become vaporized.

5. In an oil tending up through the center of said plate and discharging uel over its surface, means 'for directing alr downwardly on to the center of the said plate to spread the fuel and start the combustion, a plurality of concentric wicks set in said plate for absorbing the fuel, a groove inthe upper surfaceof the plate outside of and concentric with said wicks, means'for supplying water to said groove, a concentric series of perforations through the plate near its periphery Y for supplying air to complete the combustion,
